Sustainable Attic Insulation Choices

About Sustainable Attic Insulation Choices

An Insulation Contractor attic wastes up to 25 to 35 percent of all energy. This forces your heating and cooling system to work harder, consuming more fuel and producing more greenhouse gases. Replacing old insulation with a non-toxic option not only saves money and makes your home more comfortable, but reduces energy consumption and helps the environment.

Eco-friendly insulations are made of natural and recycled materials, or are produced with low embodied carbon (e.g., cellulose). They also typically have lower environmental impacts during manufacturing and distribution than traditional fiberglass insulation. Additionally, some eco-friendly options are hygroscopic and manage moisture differently than synthetic insulations, which promote the growth of mold and other harmful microbes.

About Attic Air Barrier Essentials

Cellulose insulation is a common green option for the attic. It is a shredded material that can be installed in open spaces like attic floors and closed wall cavities using a specialized blowing machine. This blown-in insulation can reach even small crevices, delivering a higher R-value than fiberglass batts. It is available in loose-fill form or a denser “wet” version that can be blown into closed walls to prevent settling.

Other environmentally friendly insulation options include hemp, wool, and mineral wool. They are hygroscopic, but handle moisture differently than cellulose and can be treated with borate to inhibit mold growth and provide a safer alternative for attics that are more susceptible to condensation. Lastly, high-density spray foam insulation is a great option for air sealing and is available in a variety of R-values to suit different climate zones. It has a slightly higher up-front cost than other choices, but offers superior thermal performance and long-term energy savings.
